“…World Health Organization (WHO) recognize stuttering with the code F98.5, and finalize stable definition as a speech having frequent repetition or prolongation of sounds or syllables or words, or by frequent hesitations or pauses that disrupt the rhythmic flow of speech [7,8]. It is evident from the past and concurrent literatures survey that, stuttering can be appraised a genetic disordered since 1930s [8] and employed several different dysfluencies are: interjection, revision, repetition, prolongations, and blocks.…”

Abstract-Stuttering is a speech disorder in which the person who stutters is unable to produce sounds, syllables, words or phrases as well as involuntary silent pauses or blocks. This paper presents the stuttered speech recognition system for Marathi Regional Language We collect the stuttered speech samples i.e. zero to nine spoken in Marathi language from Marathwada region. We also calculate the speech features i.e. Mel Frequency Cepstral Coefficents (MFCCs) and linear predictive coding (LPCs). We get the 75% recognition rate for MFCC and 82% for LPC. The different statistical methods will be applied to calculate the recognition rate.

“…However, changes in speech fluency may be manifested late, and these manifestations are often associated with neurological episodes, side effects of medication use, or in psychological contexts; under these conditions, the term used in the literature is acquired stuttering (13) . The term "acquired stuttering" is used with reservations in the literature, because there is discussion about considering this type of stuttering as an isolated pathology or as a symptom arising from other pathologies (1,10,(12)(13)(14)(15)(16) . Among the different types of acquired stuttering, the term neurogenic stuttering refers to a speech fluency disorder resulting from damage to the central nervous system, and it is the most frequent type of acquired stuttering (10,(12)(13)(14)(15)(16) .…”

RESUMO Objetivo Caracterizar o perfil da fluência da fala de indivíduos com Doença de Parkinson em diferentes tarefas de fala. Método Participaram do estudo 40 indivíduos, de 40 a 80 anos de idade, de ambos os gêneros, divididos em 2 grupos: GP (grupo pesquisa - 20 indivíduos com diagnóstico de Doença de Parkinson); GC (grupo controle - 20 indivíduos sem qualquer alteração de comunicação e/ou neurológica). Para todos os participantes, foram coletadas três amostras de fala envolvendo diferentes tarefas: monólogo, leitura individual e fala automática. Resultados O GP apresentou um número significativamente maior de rupturas, tanto comuns quanto gagas, e maiores porcentagens de descontinuidade de fala e disfluências gagas nas tarefas de monólogo e leitura quando comparado ao GC. Nas tarefas de fala automática, ambos os grupos apresentaram número reduzido de rupturas comuns e gagas, não apresentando diferença significante entre os grupos para esta tarefa. Em relação à velocidade de fala, tanto em palavras quanto em sílabas por minuto, os indivíduos com Doença de Parkinson apresentaram velocidade reduzida em relação ao grupo controle em todas as tarefas de fala. Conclusão O GP apresentou alteração em todos os parâmetros da fluência avaliados no presente estudo quando comparado ao grupo controle, porém esta alteração da fluência não se configura como um quadro de gagueira.

Computational modeling of stuttering caused by impairments in a basal ganglia thalamo-cortical circuit involved in syllable selection and initiation

et al. 2013

A typical white-matter integrity and elevated dopamine levels have been reported for individuals who stutter. We investigated how such abnormalities may lead to speech dysfluencies due to their effects on a syllable-sequencing circuit that consists of basal ganglia (BG), thalamus, and left ventral premotor cortex (vPMC). “Neurally impaired” versions of the neurocomputational speech production model GODIVA were utilized to test two hypotheses: (1) that white-matter abnormalities disturb the circuit via corticostriatal projections carrying copies of executed motor commands, and (2) that dopaminergic abnormalities disturb the circuit via the striatum. Simulation results support both hypotheses: in both scenarios, the neural abnormalities delay readout of the next syllable’s motor program, leading to dysfluency. The results also account for brain imaging findings during dysfluent speech. It is concluded that each of the two abnormality types can cause stuttering moments, probably by affecting the same BG-thalamus-vPMC circuit.
